Armrest, Titan rear left — a genuine BMW part, number 51 43 7 904 363. The number stamped on the part is 51437904363; BMW's catalog files it under the short number 7904363. You will find it on our Interior Body shelf, under Other Body equipment parts. It supersedes the older number 7891811, so a part carrying that number is the same part.
It fits the E46 coupe (323i, 325i, 328i, 330i and M3, 2000–2006), with the M52, M54, M56 or S54 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Retrofit, Titan-Line Interieur (03_1357) and Armrest, rear (51_3734). It weighs about 283 g (0.6 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
